CONNECTION TO THE GAS PIPELINE Once connected the burner to the gas pipeline, it is necessary to control that this last is perfectly sealed. Also verify thatthe chimney is not obstructed. Open the gas cock and carefully bleed the piping through the pressure gauge connector,then check the pressure value trough a suitable gauge. Power on the system and adjust the thermostats to the desiredtemperature. When thermostats close, the sealing control device runs a seal test of valves; at the end of the test the bur-ner will be enabled to run the start-up sequence.

ELECTRICAL CONNECTIONS All burners factory tested at 400 V 50 Hz three-phase for motors and 230 V 50 Hz monophase with neutral for auxi-liary equipment. If mains supply is 230 V 50 Hz threephase withuot neutral, change position of connectors on burneras in fig. Protect burner supply line with safety fuses and any other devices required by safety standards obtaining in thecountry in question.

OPERATION OF BURNER WITH GASBefore starting the burner, make sure it is mounted correctly. Then check connections are correct according to the dia-gram and piping is appropriate to the system. Before connecting the burner to the electricity supply, make sure voltagecorresponds to burner plate data. The connection diagram and start-up cycle are shown separately. For wiring fromcontrol box to burner, see the enclosed connection diagram. Pay particular attention to neutral and phase connections :never exchange them!. Vent air and impurities of gas pipe. Check gas pressure conforms to the limits stated on the bur-ner plate when connecting a master gauge to the test port provided on the burner. Blower motor starts and pre-purgingbegins. Since pre-purging has to be carried out with the max. air delivery, the burner control circuitturns the air damper to the max. delivery position by the air servocontrol in approximately 30 secondstime. When the servocontrol is fully open, a signal to the electronic control unit starts the 66 secondspre-purge cycle. At the end of the prepurging time, the air servocontrol gets to the Low Flame posi-tion so that burner ignition is ensured at min. output. Simultaneously the ignition transformer recei-ves voltage and after 3 seconds (pre-ignition) opens the pilot gas valve. Fuel flows to the combustionhead and ignites. Two seconds after pilot gas valves have opened, the ignition transformer is excludedfrom the circuit. In case of no ignition the burner goes to lock-out within two seconds. After 6 sec. open the workinggas valve, governed by the gas firing butterfly valve.Now the burner is operating at the min. firing rate (about 30% ofthe max. firing rate). The air servocontrol runs at the Low Flame position and in case the temperature control has to beset at the max. output it goes to a fully open position of air damper and butterfly valve. During the burner-off periodsthe air damper closes up fully.

ADJUSTING THE COMBUSTION PROCESSIMPORTANT: to obtain the right adjustment of the combustion and thermal capacity it is important to analyze thereducts of combustion with the aid of suitable instruments. The combustion and thermal capacity adjustment is donesimultaneously, together with the analysis of the products of combustion, making sure that the measured values are sui-table and that they comply with current safety standards. On this matter, please refer to the table and figure below.THESE OPERATIONS MUST BE DONE BY PROFESSIONALLY-QUALIFIED TECHNICIANS.

LANDIS & STAEFA, Model LFL1.622 OPERATING CYCLE

The control box starts the burnerfan, to carry out the prepurging ofthe combustion chamber, andcheks the vent air pressure throu-gh the air pressure switch. At theend of prepurging, the ignitiontransformer cuts-in and generatesa spark between the electrodes. Atthe same time the two gas valvesopen (Vs safety valve and Vl working valve). The total safety, in case of missed ignition or casual burner's flame-out, isgranted by a ionisation probe which cuts-in and sets the burner shutdown within the safety time. In case of gas lack or amajor pressure drop, the minimum air pressure switch shuts down the burner.

ADJUSTMENT OF THE AIR PRESSURE SWITCHUnscrew screws A and B and remove cover C.- Set the pressure switch to the minimum by turningregulator D to position 1. - Start the burner and keep in low flame running, while checkingthat combustion is correct. Through a small cardboard, progressively obstruct the air intakeuntil to obtain a CO2 increase of 0,5÷0,8% or else, if a pressure gauge is available, connec-ted to pressure port E, until reaching a pressure drop of 1 mbar (10 mm of W.G.). -Slowly increase the adjustment value of the air pressure switch until to have the burnerlockout. Remove the obstruction from the air intake, screw on the cover C and start theburner by pressing the control box rearm button.Note: The pressure measured at pressure port E must be within the limits of the pressure switch workingrange. If not, loose the locking nut of screw F and gradually turn the same: clockwise to reduce the pressure; coun-terclockwise to increase. At the end tighten the locking nut.

CHECKS TO BE MADE TO ENSURE A PROPER INSTALLATION:Before proceeding with the filling of the fuel system and subsequent burner start up, it is advisable to carryout the following checks:- Power line must be adequate to system’s adsorbed load- Fuses must be adequate to the system’s load- Boiler’s thermostats must have been properly connected- Voltage and frequency must be within the specified limits- Fuel type must be the one specified by the burner manufacturer- Feed piping section must be adequate to the requested fuel flow rate- Filters, cocks as well as fittings must have been properly installed- Blast tube length must be the one specified by the boiler manufacturer- Nozzle’s flow rate of the burner must be adequate to boiler’s output

fig. A fig. B

OPERATION OF BURNER WITH HEAVY OIL

When all the controls, as shown in previous paragraphs, have been accomplished, it will be possible to pro-ceed with the burner start up.- Switch-on the burner. When reaching the preset temperature on the working thermostat, and with boiler’sthermostat closed, the control box starts the fan, the fuel pump and the ignition transformer. At the sametime, the balancing resistors are activated, to keep fuel temperature into the heater at a constant value.- It begins, in this way, the combustion chamber prepurging, as well as the fuel circulation in the whole cir-cuit, so as to obtain an uniformity of temperature which allows a correct flowing of the same. The fuel pres-sure, during prepurging, shall be around 16÷18 bar. If not, adjust the pressure to the specifiedvalue through the regulator “D”, purposely installed on the heating circuit (see figure).- At the end of the prepurging, the control box shut off the solenoid valve “O” while openingthe 1st stage valve (for example valve “A”), allowing the burner ignition in Low Flame.Afterwards, it will be opened the 2nd stage valve “B” which, while allowing the fuel flowingthrough both nozzles, permit the burner’s High Flame ignition, i.e. at the full power.- In order to have a correct combustion, adjust the combustion air flow for both Low and High flame.During flow rate adjustement, it is possible to manually switch from Low Flame to High Flame and viceversa,through the LOW/HIGH manual switch. When all adjustments are made, leave the switch in II (HIGH)position.- The fuel pressure during burner’s working shall be set to 23 bars.

CLEANING AND MAINTENANCE OF FILTERS MOUNTED ON THE PREHEATER

REMOVING OF THE FILTER1. Switch-off the burner.2. Loosen screw B and drain part of the fuel from the heater, until the fuel level drop below the filter.3. Unscrew and pull out the stem filter A from its seat.4. Clean the filter and reassemble the parts as shown by the picture, then fit it in its own seat.It is advisable to replace all filter and valve gaskets whenever they are removed.

Note that when the burner is working the heater has a pressure of abt. 23 bar, and that it becomes very

dangerous to carry out said operations with the burner running.

SETTING PARAMETERSWhen the burner is ignited all displays of the regulator light up. The set point display will blink for about 10 seconds. The valuein the upper field of the display (red) indicates the actual value. The value in the lower field of the display (green) indicates the setpoint currently programmed. CHANGING THE SET POINTTo change the set point, proceed as follows: ---- Press the PGMPGM button to access the user level. SP1* will appear in the lower display---- Change the value of set point SP1 using the t and s keys.▼e ▲. ---- After a 2 second delay the value set is stored automatically – Toreturn to normal display press EXITEXIT. ** The value of SP1 depends on the value set previously in configuration level C111.SETTING PID PARAMETERSPID parameters are factory set to standard mean values. The operation of the regulator can be self-adapted to suit the system byactivating the “tunE” function. The regulator will set the PID parameters automatically. To activate the “tunE” function proceedas follows: ---- With the burner in operation, press PGM PGM + ▼. ---- the caption “tunE*” will blink in the display. – When “tunE” stopsblinking, the self-adaptation routine has been completed. ---- Confirm the computed parameters by pressing the ▲ key for 2 seconds. ** The “tunE” function cannot be activated in Manual mode, or when the burner is off. The PID parameters can be corrected manually from the parameters level, working on the proportional band Pb1, the derivati-ve action time dt and the integral action time rt. To change parameters Pb1, dt and rt, proceeds as follows: ---- Press the PGMPGM button to access the parameters level. ---- To move fromone parameter to the next, press PGMPGM . ---- When Pb1 is displayed, the value can be increased or decreased using the s and t keys. ----Confirm the changed parameters by pressing PGMPGM. ---- If confirmation is not given within 2 seconds the value will be stored auto-matically. ---- Press PGMPGM to access the next parameter. ---- When dt is displayed, repeat the procedure described above. ---- Press PGMto access the next parameter. ---- When rt is displayed, repeat the procedure above. ---- To return to normal display press EXITEXIT. DIFFERENTIAL SETTING FOR IGNITION AND SHUTOFFThe regulator allows the selection of an adjustable switching differential that establishes burner ignition and shutoff values.HYS1 indicates the lower ignition limit, below which the regulator switches the burner to maximum power. HYS3 indicatesthe upper shutoff limit, above which the regulator switches the burner off. To set HYS1 and HYS3 proceed as follows: ---- Pressthe PGMPGM key to access the parameters level. ---- To move from one parameter to the next, press PGMPGM . ---- When HYS1 is displayed(burner ignition differential-stage II), increase or decrease the value using the ▼ and ▲ keys. ---- Confirm the changed parameters bypressing PGMPGM. ---- If confirmation is not given within 2 seconds the value will be stored automatically. ---- Press PGMPGM to access thenext parameter. ---- When HYS2 is displayed (burner shutoff differential-stage II), repeat the procedure described above. ---- PressPGMPGM to access the next parameter. ---- When HYS3 is displayed (upper shutoff differential) repeat the procedure described above. ---- To return to normal display press EXITEXIT.

MANUAL/AUTOMATIC MODETo access “MANUAL” mode, press and hold EXITEXIT for at least 5 seconds. Manual mode can only be selected when the burner isin operation. It is deactivated automatically when the burner shuts off. When the LED above the hand symbol is alight, the regu-lator is in manual mode and the position of the servocontrol can be changed using the ▼ and ▲ keys. The LEDS on the front ofthe regulator indicate whether the servocontrol OPEN or CLOSE command is currently active. Pressing the ▼ key the servocon-trol OPENS. Pressing the ▲ key the servocontrol CLOSES. To select automatic mode press and hold EXITEXIT for at least 5 seconds.The LED above the hand symbol goes out and the regulator reverts to automatic.

CLIMATIC COMPENSATIONThe RWF 40 regulator can be set with the set point interlocked to the external probe. To select this operating mode, proceed asfollows: ---- Connect the required probe as in the wiring diagram. ---- Change the regulator settings. When using an external probethe regulator must be set as follows: ---- Press the PGMPGM key to access the configuration level. When the caption C111 (XXXX) isdisplayed, use the ▲ key to access the second figure (XXXX). Use the ▼ key to select the type of probe (XX3X). ---- Confirm thechange of parameters by pressing PGMPGM. If this is not done within 2 seconds, the value is stored automatically ---- Press PGMPGM toaccess the configuration level. When the display reads C112 (XXXX), use the ▲ key to access the second figure (XXXX). Press the▼ key to set the type of probe (XX3X). ---- Confirm the changed parameters by pressing PGMPGM. ---- If confirmation is not givenwithin 2 seconds the value will be stored automatically. ---- To return to normal display press EXITEXIT. To establish the heating curve, proceed as follows: ---- Press PGMPGM to access the parameters level. ---- Press PGMPGM to move from one parameter to the next. ---- When the letter H isdisplayed (heating curve gradient), increase or decrease the value using the ▼ and ▲ keys. ---- Confirm the changed parameters bypressing PGMPGM. ---- If confirmation is not given within 2 seconds the value will be stored automatically. ---- To return to normal display press EXITEXIT.

MAINTENANCEANNUAL CHECKThe burner (combustion head, electrodes, etc.) must be checked regularly by an authorized technician, once or twicea year, depending on how much it is used. Before proceeding withe the maintenance check-up on the burner, it isadvisable to check the general condition of the burner and take the following steps: Disconnect the burner (removethe plug). - Close the gas shut-off cock. - Remove the cover from the burner, clean the fan and air intake. - Clean the combustion head and check the position of the electrodes. - Re-install the parts. - Check the seal on the gas connectors. - Check the state of the flue. - Start the burner. - Check the combustion parameters

BEFORE TAKING ANY ACTION, CHECK:- that there is power in the circit and the burner is connected; - that the gas pressure is right and the gas shut-off cock is open; - that the control systems are properly connected. If all these conditions have been satisfied, start the burner by pres-sing the reset button. Check the burner cycle.

IF THE BURNER FAILS TO START:check the switch, the thermostats, the motor and the gas pressure, fuses burnt, resistors failure, heater thermostats open.

IF THE BURNER PROCEEDS WITH PREVENTILATION BUT CUTS OUT AT THE END OF THE CYCLE:check the air pressure and the fan. Check the air pressure switch, UV cell failure, premature ignition due to oil leakagefrom solenoid valve.IF THE BURNER PROCEEDS WITH PREVENTILATION BUT DOES NOT LIGHT:check the installation and position of the electrodes. Electrodes dirty. Nozzles clogged. Check the ignition cable. Check the ignition transformer. Check the safety device. Eccles of combustion air related to nozzles flow rate.

IF THE BURNER LIGHTS BUT CUTS OUT AFTER THE SAFETY INTERVAL: check that the phase and neutral wires are connected correctly. Check the gas solenoid valve. Check the UV cell. Check the safety device. The oil pressure during prepurging is too low.Filters clogged. Nozzles are too worn. The oil temperature is too low (flame jumps). Eccles of combustion air related to nozzles flowrate

IF THE BURNER LIGHTS BUT CUTS OUT AFTER OPERATING FOR A FEW MINUTES:check the pressure regulator and gas filter. Check the gas pressure with a pressure gauge. Check the detector value (atleast 70 µA).
